Another` object of the invention, is torofde a tjc in which the pl1mti-lercsistmgmembers, be-'ng'flexible, will in no wise defunct. from lthe flexibility of the article.

One form which my invention muy hike, is disclosed in n Single cross-suctinnnl view, in the. drawings.

` ."[n carrying out the invention, there is l which muy be con stmcteclalong any line dictated by the, experience of 'those skilled in the art to which the inxfention uppextains. Ordinarily, the

casingil ismade-of rubber, rubberized fabric,

orf aJ combination of these 0r ailier materials. Tf 1s cmmon to provide such n part asV thc of @some kind, forming a more or less Vpronounced tread. The. casing l is suflably com.

At. tyl1e salme time. howevm-,ha lavora 4 of nettin will afford an ade uate `proteetion against puncture, and Wi serve to a marked and important degree, as a reenforcement for the casing.

5 The device forming the subject matter of this application embodies a tire casing which will' resist puncture, the easing being devoid of stiffness, infiexibility, and those other eoncomitent disadvantages which arise when a 10 tire casing is reenforced by metal plates,

either perforated or imperforete.

I claim In a device of the class described, a tire casingr comprising layers of rubberized fabric, between which a, layer of line mesh 15 wire nettingr is interposed and vulcanized, the netting being fiexhle and being fashioned from moisture-resisting material, the netting being (-oated with tenacious, `resilient, vuleanizuble cement, which is in a partially dried condition prior to the mount ing of the netting between the layers of fabric.

In testimony that I claim the foregoing as my own, I have hereto aixed my signa- 25 ture.
